Gravity Labs

Features
Read full description

The device itself is the lab instrument! Gravity Lab turns your iPhone or iPad into a pocket physics playground for young scientists aged 8–12. TILT TO EXPERIMENT Steer a marble through 8 hand-crafted mazes just by tilting the device. Dodge the holes, find the gaps, reach the flag — and feel how real physics behaves while you do it. FEEL THREE GRAVITIES • Earth — the world you know • Moon — 1/6 gravity, the marble floats like an astronaut • Jupiter — 2.4× gravity, heavy and fast! Some levels even switch gravity mid-run. Adapt, scientist! ICE OR SAND Slippery ice barely slows the marble; grippy sand brakes it fast. Friction stops being a textbook word the moment you feel the difference. LEARN WITHOUT READING A TEXTBOOK Every finished level shows a one-line Lab Note — a real science fact about what just happened. Galileo's marble experiment, why ice is slippery, how astronauts jump higher: science sneaks in one line at a time. EARN LIKE A SCIENTIST • 1–3 stars per level for speed and precision • Coins to spend on marble skins (galaxy, lava, glitter) • 6 scientist badges: Friction Finder, Gravity Guru, Momentum Master and more • A daily lab streak for coming back to experiment MADE FOR KIDS, TRUSTED BY PARENTS • No ads, no in-app purchases, no tracking • No account, no internet needed — works fully offline • No reading required to start playing • All progress stays on the device • Prefer not to tilt? Finger-steering mode is in Settings Pick up the lab. Tilt it. That's the whole instruction manual.

Verdict

The call

The clearest difference is in-app purchases: Gravity Labs at none against Queens Puzzle's 1. Gravity Labs also leads on ads (none vs shown). Queens Puzzle's advantage is iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.
